EMS messages are just SMS messages with a twist.<\/p>\n<p>EMS messages make use of the User Data Header to add some meta data to the <a href=\"https:\/\/mobiletidings.com\/sms-via-email\/\" target=\"_blank\" rel=\"noopener\">SMS message<\/a> being sent. This meta data is separate from the actual text and devices that don\u2019t understand some or any of the EMS features will easily skip over them and just render the text.<\/p>\n<p>The uses of EMS are many:<\/p>\n<h4 id=\"ems-lets-you-group-a-number-of-sms-messages-into-one-large-message\">EMS lets you group a number of SMS messages into one large message<\/h4>\n<p>Normal SMS messages can have 140 octets of payload. GSM-7 is a 7 bit alphabet, so when encoding text in the default GSM-7 alphabet you can send 160 characters (septets) in a single message.<\/p>\n<p>EMS lets you add metadata that says \u2018this is message 1 of 3\u2019. If the receiving device understands this EMS feature it will wait for all parts to arrive and render them as one big message. If it doesn\u2019t the device will show the parts as individual messages. See <a href=\"https:\/\/mobiletidings.com\/combining-sms-messages\/\" data-abc=\"true\" target=\"_blank\" rel=\"noopener\">combining SMS messages<\/a>\u00a0for more details.<\/p>\n<h4 id=\"ems-lets-you-add-some-basic-formatting-to-your-messages\">EMS lets you add some basic formatting to your messages<\/h4>\n<p>Through EMS you can control:<\/p>\n<ul>\n<li>Alignment of text (choices: left, center, right)<\/li>\n<li>Font size (choices: normal, large or small)<\/li>\n<li>Font style (options: bold, italic, underlined and\/or strikethrough)<\/li>\n<li>Text color (choose from 16 colors)<\/li>\n<li>Background color (choose from 16 colors)<\/li>\n<\/ul>\n<p>More details on how to achieve this in the post \u201c<a href=\"https:\/\/mobiletidings.com\/text-formatting-sms-ems\/\" data-abc=\"true\" target=\"_blank\" rel=\"noopener\">Text formatting with EMS<\/a>\u201c.<\/p>\n<h4 id=\"ems-lets-you-add-sounds-to-your-message\">EMS lets you add sounds to your message<\/h4>\n<p>You can choose from 10 predefined sounds like \u2018chimes\u2019, \u2018ding\u2019, \u2018ta-da\u2019, \u2018claps\u2019 or create your own sound using the iMelody format.<\/p>\n<h4 id=\"ems-lets-you-add-pictures-to-your-message\">EMS lets you add pictures to your message<\/h4>\n<p>You can choose from 15 predefined smileys like \u2018I am glad\u2019, \u2018I am laughing\u2019, \u2018In love\u2019, \u2018I am winking\u2019 or create your own image using a bit array representing black and white pixels.<\/p>\n<h4 id=\"other-features-available-through-ems\">Other\u00a0 features available through EMS<\/h4>\n<p>These are less frequently used, but you can add<\/p>\n<ul>\n<li>Animations<\/li>\n<li>Scalable vector graphics<\/li>\n<li>Embedded vCards<\/li>\n<li>Embedded vCalendar items<\/li>\n<\/ul>\n<p>Again EMS is designed so that devices that don\u2019t understand EMS at all will just ignore all the EMS features. Even if a device supports EMS, it is unlikely to support every option available. The design of EMS lets devices also easily skip unsupported features.<\/p>\n<p>If you want to send EMS messages using a GSM modem, you\u2019ll have to use PDU mode. Note that if you use a phone as an SMS modem, the phone used for sending doesn\u2019t need to understand EMS. The PDU mode lets you format messages in any way possible without relying on any other feature of the modem in use.<\/p>\n<p>In a future post I\u2019ll construct some EMS messages to show you how it works in detail.<\/p>\n","protected":false},"excerpt":{"rendered":"EMS stands for Enhance Message Services.
